(Cl. iwi- 172) 3 Claims.

This invention relates to a clean tip for type-A writer ribbons.

The invention aims to provide, in a manner as hereinafter set forth, a means to facilitate the renewing of a typewriter ribbon-easily, speedily,

' correctly and reducing to a minimum the soiling of the fingers during the renewing-operation.

The clean tip includes a'coupling element, generally indicated at Il and a protecting element,

' generally indicated at I2.

'.he invention further aims to provide, in a The invention further aims to provide, in a manner as hereinafter set forth, a clean tip for typewriter ribbons which is simple in its construction and arrangement, strong, durable, compact, thoroughly eicient in its use, andr inexpensive to manufacture.

Embodying the aims aforesaid and others which may hereinafter appear, the invention con' sists of the novel construction, combination and arrangement of parts as will be more specifically referred to and illustrated in the accompanying drawings wherein is shown an embodiment of the invention, but it is to be understood that changes, variations and modifications may be resorted to which fall Within the scope of the invention as claimed.'

In the drawing: f

Figure l is a front elevation of an end terminal portion of a new ribbon and an end terminal portion of an old ribbon, showing the adaptation therewith of a clean tip, in accordance with this invention, during the renewal operation,

Figure 2 is a rear elevation of an end terminal portion of a new ribbon showing the adaptation therewith of a clean tip, in accordance with this invention, and with the other element of the clean tip not shown,

Figure 3 is a fragmentary view in front eleva.- tion of an end terminal portion of a new ribbon provided with means correlating with an element of the tip for connecting them together,

Figure 4 is a rear elevation of the coupling element of the tip,

The element II preferably will be constructed of fabric of tape-like form and it includesy an inner end portion I3, an intermediate portion I4, and a tapered end portion I5. The portion I3 merges into the portion I4 and adjacent the 'point of ni'rgence the element II is formed with a pair of oppositely extending notches I6, I1 disl -posed transversely with respect to the body of element Ii and opening at its lengthwise edges thereof- The portion I3 on its longitudinal median is formed with a slot I8 spaced from the free end of the portion I3 and the point of mergence between the portion I3 and the portion i4. The element II betweenthe notches I6,

Il is s cored, as at I9. The element II at the pointvof mergence of the portions I4, I5 is provided -with a transverse score 20. The portion I4 is of longitudinal contour and of greater length than the portions I3, I5. The portion I3 is of substantially rectangular contour and correspends in `width to the width of the portion Il.

s IIhe rear face of the element I4 is provided with a cementitious coating 2|, which extends from the score I9 to the free end of the portion l5. The notches I6, I1 correlate with the slot 8 for connecting the element II to the end portion 8 of the new ribbon. In this connection it will be stated that the portion I3 of the element I'I is bent upon itself to reduce its width and then extended through the slot 9after which the said bent portions assume the position shown in Figures land 2, and the rearv face of the ribbon is pressed rmly to cementitious strip on front face of portion I3, whereby the end terminal portion 8 of the new ribbon is connected to the element II. n

When the end portion I3 of the element II is connected to the terminal portion 8 of the new ribbon, said end portion I3 opposes the inner face 'of the terminal portion 8, as is shown in Figure 6, and that part of the' terminal portion 8 outwardly with respect to the slot 9 is arranged on and secured to the rear face of the element Il by a portion 'of the Acementitious material 2|. The notches I6, 81, when the element I I is secured to the terminalportion B, permit of the terminal portion I3 being bent upon itself, so as to extend through the slot 9.

The protecting element I2 consists of a strip of fabric of tape-like formfand it includes an inner end portion 22, an intermediate portion 23 and an outer end portion 24. The portion 22 merges into the portion 23 and the latter merges into the portion 24. The portion 22 is substantially rectangular as well as the portion 23. The portion 23 is tapered. The element I2 conforms in contour to that part of the element II extending from the notches I 6 to the free end of the portion I5. At the point of mergence of the portions 22 and 23 the element I2 is scored, as at 2 5. The inner face of the element I2, which may be termed the forward or front face thereof, with respect to the element Il is formed with a body of cementitious material 26 which extends throughout such face from the scor 25 to the free end of the portion 2l.

It will be assumed that the clean tip is inthe position shown in Figure 2 and attached to the terminal portion 8 of the new ribbon and when so ypositioned the clean tip is ready for change of ribbons in a machine.

By running off all but about a foot of the old ribbon on the right old spool, one is ableto release the right spool, keeping the old ribbon threaded throughall the slots and ribbon bars. The spool is then drawn to the left, placing it on a flat surface where attaching the new ribbon to the old ribbon may be carried out. It will be stated that the element I2 is removably mounted on the element II, prior to the renewing operation.' The Old ribbon I0 is then secured by the cementitious material 2I to the element II, such as is shown in Figure 6, and by pressing down on the old ribbon smoothness will be insured. Now one rewinds the right old spool, drawing clean tip and new ribbon carefully first through the right hand slot, second through the rlbbon'bar where type strikes,.third through the left hand slot always keeping the new spool at the level of the spindle until excess ribbon is rewound and then it may .be placed in its correct DOsition in the right hand spindle. Next, remove the right hand old ribbon spool by drawing it to the left. It will be added that the old ribbon is also secured by the protecting element I2 to the element Il, such as shown in Figure 6.

After the removal of the right hand old ribbon 'spool by drawing it to the left, the element I2 is `removed and the old ribbon pulled off of element H. The element Il is folded back on itself on score 2o; this will give one a tab to pull the new ribbon to lock or catch in slot i8 into the hook of the empty spool, which is then inserted on the left hand spindle. That portion of element Ii outwardly of the terminus of theportion 8 from the point 2'? (shown in Figure 6) is then .sive coating.

cut-o after which the machine can be for rewinding the ribbon. Y; I

What I claim is:
